Application

1,2-Diiodoethane can be used:
  • To synthesize samarium(II) iodide-water complex (SmI2-H2O complex), a single-electron transfer reagent, to further synthesize 3-hydroxy carboxylic acids.
  • To synthesize derivatives of regioselective homopropargyl alcohols by using sonochemical Barbier-type reaction conditions.
  • As an iodine source and an effective reagent for the dehydroxy-iodination of alcohols.
